Python Windows:AttributeError:Can'；t获取属性"；abc"；,python,jupyter-notebook,multiprocessing,Python,Jupyter Notebook,Multiprocessing,我尝试运行一个简单的命令，使用多处理按名称猜测性别。这段代码在以前的机器上运行，所以我的设置可能与此有关 下面是我的多处理代码： import sys import gender_guesser.detector as gender import multiprocessing import time d = gender.Detector() def guess_gender (name): n = name.title() # make first letter upper ca

我尝试运行一个简单的命令，使用多处理按名称猜测性别。这段代码在以前的机器上运行，所以我的设置可能与此有关

下面是我的多处理代码：

import sys
import gender_guesser.detector as gender
import multiprocessing
import time

d = gender.Detector()

def guess_gender (name):
    n = name.title() # make first letter upper case and the rest lower case 
    g = d.get_gender(n) # guess gender
    return g

ls = ['john','joe','amamda','derick','peter','ashley','john','joe','amamda','derick','peter','ashley']

t=time.time()

results=[]
def callBack(x):
    results.append(x)

pool = multiprocessing.Pool(processes=multiprocessing.cpu_count()-1, maxtasksperchild=1)

for n in ls:
    print (n)
    pool.apply_async(guess_gender,args=[n],callback=callBack)

pool.close()
pool.join()

results = pd.concat(results)

print(time.time()-t)
它只是运行，什么也不做。在我的cmd窗口中，我在错误消息的末尾看到以下内容：

AttributeError: Can't get attribute 'guess_gender' on <module '__main__' (built-in)>
更新：仍然无法使其工作。下面是我运行提供的代码时的整个cmd日志。我很感激你的任何想法
